Texas Instruments Introduces CDC3S04, the Industry’s Smallest Four-Channel, Low-Power, Low-Jitter Sine-to-Sine Wave Clock Buffer

November 28th, 2009, by pur, in IC/Chip/SoC, Industrial, Semiconductor

The CDC3S04 is a four-channel low-power low-jitter sine-wave clock buffer. It can be used to buffer a single master clock to multiple peripherals. The four Outputs sine-wave outputs (CLK1–CLK4) are designed for minimal channel-to-channel skew and ultralow additivejitter. The CDC3S04 is the first device in a family of sine-wave clock buffers. The CDC3S04 can replace up to three individual same-frequency temperature compensated crystal oscillators (TCXOs), reducing board space and bill of materials (BOM) by nearly half. Designers can use the CDC3S04 in a wide range of mobile applications including cell phones (UMTS/WCDMA/GSM), smartphones, mobile internet devices (MID), ultra mobile PCs (UMPC), navigation units and global positioning systems (GPS)…

Texas Instruments Incorporated (TI) (NYSE: TXN) introduced the industry’s smallest four-channel, low-power, low-jitter sine-to-sine wave clock buffer, the first device in a family of sine-wave clock buffers. The CDC3S04 can replace up to three individual same-frequency temperature compensated crystal oscillators (TCXOs), reducing board space and bill of materials (BOM) by nearly half. Designers can use the CDC3S04 in a wide range of mobile applications including cell phones (UMTS/WCDMA/GSM), smartphones, mobile internet devices (MID), ultra mobile PCs (UMPC), navigation units and global positioning systems (GPS).

Key features and benefits of the CDC3S04

  • 1:4 low-jitter, sine-to-sine clock buffer replaces multiple TCXOs, saving board space and cost
  • An integrated on-chip LDO saves board space by eliminating the need for an internal low-dropout (LDO) regulator.
  • The on-chip LDO acts as a TCXO on/off switch for power savings during low-power standby
  • This buffer distributes sine-wave signals to four different peripherals while adding negligible phase-noise, minimizing electromagnetic interference (EMI).
  • A built-in I2C interface gives customers real-time control for outputs, polarity and internal coding.
  • Designers can accelerate time-to-market by taking advantage of TI’s OMAP4xx processors.

Availability and pricing

The CDC3S04 is in volume production today, and evaluation modules (EVMs) will be available in late 4Q09. The CDC3S04 comes in an industry-leading, small-footprint WCSP package (1.6 mm x 2.0 mm), and is priced at $1.80 in 1,000-unit quantities.
